Do you mean that it will only fire air with the firebolt/ no QEV or do you mean with the L7/QEV?

Is your loader also able to feed fast enough?

You should pull off the QEV and put on the stock banjo to see if the QEV is causing the issue. I'm assuming either your QEV is somehow malfunctioning or your board settings are incorrect for your set up, therefore not operating correctly. If it fires normally with the L7 bolt and the stock banjo, then you should switch your settings around with the QEV.

Your dwell appears to be in the correct area, but you may need to increase your ROF delay.

Test to see whether the bolt or the QEV is the issue because bolt is lighter with a higher flow rate and the QEV is also an increase in airflow. Try bumping your ROF up to 8-10 and see if that makes a difference.
